About Derma Roller For Hair Loss

does dermaroller work for hair loss

Often times people face hair loss problems when their scalp and hair follicles are badly in need of stimulation. This is why several studies suggest dermarolling (microneedling) as an effective hair loss treatment.

A dermaroller is a plastic tool that makes tiny pricks in your skin with its micro-needles. The titanium needles of the device make pricks that penetrate into your dermal layer of the skin. The micro-needles penetrate just deep enough to boost your circulation and help create new production of cells. 

This process should be painless and is not known to inflict any damage. In fact, the penetration with the needle pricks not only can induce the collagen production to cure hair loss, but it also can cure imperfections on your skin.

The sizes of the pins vary between 0.2 to 2 millimeters. The device rolls these needles over your skin, thereby making small punctures in a large number on the upper layers of your skin. The treatment is very simple and that can be easily implemented at home.

Dermarollers for Hair Growth

When you roll a dermaroller across your scalp, the device makes a large number of tiny punctures all over the surface. Experts believe that your body reacts to the several tiny wounds that your dermaroller creates. The body floods the subjected area with wound-healing and inflammatory molecules, stimulating the area to help promote new hair growth. 

The Science behind Dermaroller’s Benefits for Hair Loss

The tiny punctures that a dermaroller makes across your scalp increase the blood circulation and the cell production, thereby helping stimulate new hair growth.

Microneedles are beneficial in stimulating the skin cell proliferation. As per the claims of researchers, the positive effects of microneedling on skin cell proliferation are also beneficial for scars, wounds and hyperpigmentation treatment. However, it is most effective for growing new hair

According to the researchers, this process of healing includes three stages. They are:

  • Inflammation 

  • Proliferation 

  • Maturation (remodeling)

Dermarollers are not known to cause any damage to your scalp, as the needles of the device only penetrate to a certain depth. The needles only penetrate deep enough to initiate your healing process and to trigger the proliferation of skin cells.

Follow along as we discuss how to use a dermaroller on your scalp.

1.) Pick the size of your needle

If you research micro-needling and hair loss, you will see that it suggests a needle of 1.5 millimeters as the most common length for treating hair loss. This size coordinates with the depth of the penetration, as your hair follicles sit between 1 to 2 millimeters deep within your dermis. This is the exact depth of penetration that you require. You can also use shorter needles, but they might not be as effective. Keep in mind that the longer the needle, the more painful it will be due to how far it is penetrating the skin tissue.

2.) Wash your hair thoroughly and sterilize the dermaroller

3.) Use a wide-tooth comb to brush your hair

In order to make sure you have effectively penetrated all areas of the scalp, go over each area several times before completing treatment.

Once you complete the entire treatment, you may use a natural hair growing oil.. These can provide nourishment to your freshly penetrated follicles and potentially boost your hair growth efforts. 

How Often Should You Dermaroll Your Scalp?

This varies depending on the size of the needle you are using on your scalp. If you plan on starting out using a needle less than 0.5 mm, you can complete treatment every other day.

The longer the needle, the longer you will have to wait in between treatments. For example, if you use the requested needle size of approximately 1.5 mm, complete treatment about once every week.

However, see how your scalp feels overall and how many treatments it can tolerate. If you have to do treatment once a month, that will be fine. You do not want to inflict intolerable pain throughout this process.
